FAQ
Why is octal output three digits per group?
A byte maxes at 255, which is octal 377 — exactly three digits — so each byte is zero-padded to three digits for alignment.
How does it differ from hexadecimal conversion?
Both use UTF-8 bytes, only the base differs: octal digits are 0-7 and need more positions, commonly seen in Unix permission notation.
Will my data be uploaded?
No, all conversion runs locally in your browser, nothing is uploaded.
